If it is a typical impusle-type noise blanker, you might
not be as impressed with its performance under crowded
band conditions.  The blankers on my IC-765's work great,
*except* in crowded band conditions, like a radio contest.
I'll leave the explanation of why this is to someone who 
can explain it better than I could.

Line noise really has to be dealt with at the source,
in my experience.  Definately rule out local (in home)
sources first.  Keep good records when it comes time to 
deal with the power utility.

Good luck, and please keep us informed of your progress.
